Legal Question in Wills and Trusts in North Carolina

First, I don't know what a "closure" is or why you sent it your ex-husband.

Unless he defamed you, I'm not certain that your ex-husband committed any torts. You chose to send the email to your ex-husband. While it was private, the fact is that you sent it. Once sent, your ex-husband could do anything he wanted to with it unless you had some kind of a confidentiality agreement in place, which would be unlikely.

Litigation is very costly. Even if you can bring some kind of action for violation of your privacy and you get a restraining order against him, what will that accomplish? Do you have money for a lawyer? And its not harassment by contacting someone once. If he is continuing to do it, then it becomes harassment and that is indeed a crime. However, you can't complain about your ex-husband contacting someone else. Your employer or co-workers, if they are the recipients of the harassment, would have to go to the police.

You opened this can of worms by sending the email. I don't know why you did that but hopefully, this can all just die a quiet death and will soon be forgotten. If you pursue legal action, you are going to make this worse and keep this alive.

This is just my opinion. I am not a litigation attorney and this question has nothing to do with probate, trusts wills & estates (which covers the disposition of assets once you are dead or the proposed distribution in the event of your death). Perhaps another attorney will answer you. Or you can go to a general tort/personal injury attorney to see if this conduct would be actionable and if so, get a ballpark on the cost before you commit to legal action.
